Abstract: Foam control compositions herein can be used in aqueous compositions that are liable to foam. The foam control compositions is added to detergent compositions, particularly detergent powders, to inhibit excessive foaming when the detergent is used in washing. In particular, the foam control composition contains a non-silicon-containing organic liquid, a branched siloxane resin, a particulate filler which is insoluble in the organic liquid, and an additive composition of melting point 35 to 100° C. that is substantially non-polar organic material which is miscible with the organic liquid.

Abstract: A foam control composition contains a liquid polymer of an unsaturated hydrocarbon, a branched siloxane resin, and a particulate filler which is insoluble in the liquid hydrocarbon polymer. The foam control composition can additionally contain a polysiloxane fluid.

Abstract: A foam control agent, comprising (A) an organopolysiloxane material having at least one silicon-bonded substituent of the formula X-Ph, wherein X denotes a divalent aliphatic organic group bonded to silicon through a carbon atom and Ph denotes an optionally substituted aromatic group, (B) a water-insoluble organic fluid, (C) an organosilicon resin and (D) a hydrophobic filler. The foam control agent may be provided as an emulsion or as a particulate material. It is especially useful as a detergent foam control agent.

The organosilicon resin (B) preferably consists of siloxane units of the formula R′aSiO4−a/2 wherein R′ denotes a hydroxyl, hydrocarbon or hydrocarbonoxy group, particularly trialkylsiloxy units and SiO4/2 units, wherein a has a value of from 0.5 to 2.4. The foam control agent may be provided as an emulsion or as a particulate material. It is especially useful as a detergent foam control agent.

Abstract: The foam control efficiency of a silicone antifoam in liquid or powder detergent formulations is improved by the use as an additive of an olefinically unsaturated alcohol, for example oleyl alcohol.
